Want to stop postal junk mail? Now there’s an app for that. Americans can use their iPhones and iPads to eliminate unwanted mail with the new MailStop™ Mobile app from Catalog Choice—the nation’s leading mail preference company.

The free app is available for download in the iTunes App Store. Once installed, members login or create a free Catalog Choice account, take pictures of their unwanted mail and upload those images to www.catalogchoice.org. Catalog Choice will then communicate opt-out requests to companies and monitor compliance. The MailStop™ Mobile app works in sync with one’s free online account and is used to opt-out of all types of direct mail including catalogs, credit card offers, donation requests and coupons. The first five MailStop™ Mobile opt-outs are free. Members can buy additional opt-outs within the app priced at $1.99 for five, $6.99 for 20 or $14.99 for 50.

MailStop™ Mobile is the newest service in a line of premium opt-out tools from Catalog Choice, including MailStop™ Envelopes and MailStop™ Shield. A version of the MailStop Mobile app will be available for Android users in 2012.
